Father's Emotional Plea to Andrew Koenig: 'Are You Okay?'

Fighting tears, Walter Koenig looked into the news cameras on Wednesday desperately hoping his missing son was watching.

"I just want to know you're okay," he said in the emotional appeal to Andrew Koenig, the Growing Pains star who disappeared earlier this month. "If it means you just want to stay here, that's okay. You don't have to come back. Just let us know that's your intention."

Walter Koenig, also an actor – he played Mr. Chekov on the original Star Trek TV show and movies – was joined by wife Judith at the televised press conference at the Vancouver Police Department.

Police say the younger Koenig was last seen in the British Columbia city on Feb. 16, the same day his phone and ATM activity stopped. The search most recently went to a Vancouver park he frequented, but mounted officers found no sign of the 41-year-old Koenig.

Koenig, who had long battled depression, cleared out his Los Angeles apartment about three weeks ago before traveling to Vancouver, where he once lived. Constable Tim Fanning says police were hopeful Koenig was still in the area and "doesn't want to be found."
